Trazodone, sold under many brand names,[1] is an antidepressant medication,[20] used to treat major depressive disorder, anxiety disorders, and insomnia.[20] It is a phenylpiperazine compound of the serotonin antagonist and reuptake inhibitor (SARI) class.[21][22] The medication is taken orally.[20]

Common side effects include dry mouth, feeling faint, vomiting, and headache.[20] More serious side effects may include suicide, mania, irregular heart rate, and pathologically prolonged erections.[20] It is unclear if use during pregnancy or breastfeeding is safe.[23] Trazodone also has sedating effects.[24]

Trazodone was approved for medical use in the United States in 1981.[20] It is available as a generic medication.[20] In 2022, it was the eighteenth most commonly prescribed medication in the United States, with more than 27 million prescriptions.[25][26]
